1 SARDAR RAJA COLLEGE OF ENGINEERING RAJA NAGAR, ALANGULAM DEPARTMENT OF MECHANICAL ENGINEERING Subject Name : ENVIRONMENTAL SCIENCE AND ENGINEERING Subject Code : GE 2021 Year/Branch : III BE / MECH Semester : V Prepared By, N.JAYAKUMAR Assistant Professor /Chemistry Humanities and Science Department

2 GE 2021 ENVIRONMENTAL SCIENCE AND ENGINEERING L T P C AIM The aim of this course is to create awareness in every engineering graduate about the importance of environment, the effect of technology on the environment and ecological balance and make them sensitive to the environment problems in every professional endeavor that they participates. OBJECTIVE At the end of this course the student is expected to understand what constitutes the environment, what are precious resources in the environment, how to conserve these resources, what is the role of a human being in maintaining a clean environment and useful environment for the future generations and how to maintain ecological balance and preserve bio-diversity. The role of government and non-government organization in environment managements. UNIT I ENVIRONMENT, ECOSYSTEMS AND BIODIVERSITY 14 Definition, scope and importance of environment need for public awareness concept of an ecosystem structure and function of an ecosystem producers, consumers and decomposers energy flow in the ecosystem ecological succession food chains, food webs and ecological pyramids Introduction, types, characteristic features, structure and function of the (a) forest ecosystem (b) grassland ecosystem (c) desert ecosystem (d) aquatic ecosystems (ponds, streams, lakes, rivers, oceans, estuaries) Introduction to biodiversity definition: genetic, species and ecosystem diversity biogeographical classification of India value of biodiversity: consumptive use, productive use, social, ethical, aesthetic and option values Biodiversity at global, national and local levels India as a mega-diversity nation hot-spots of biodiversity threats to biodiversity: habitat loss, poaching of wildlife, man-wildlife conflicts endangered and endemic species of India conservation of biodiversity: In-situ and ex-situ conservation of biodiversity. Field study of common plants, insects, birds Field study of simple ecosystems pond, river, hill slopes, etc. UNIT II ENVIRONMENTAL POLLUTION 8 Definition causes, effects and control measures of: (a) Air pollution (b) Water pollution(c) Soil pollution (d) Marine pollution (e) Noise pollution (f) Thermal pollution (g) Nuclear hazards soil waste management: causes, effects and control measures of municipal solid wastes role of an individual in prevention of pollution pollution case studies disaster management: floods, earthquake, cyclone and landslides. Field study of local polluted site Urban / Rural / Industrial / Agricultural. UNIT III NATURAL RESOURCES 10 Forest resources: Use and over-exploitation, deforestation, case studies- timber extraction, mining, dams and their effects on forests and tribal people Water resources: Use and over-utilization of surface and ground water, floods, drought, conflicts over water, dams-benefits and problems Mineral resources: Use and exploitation, environmental effects of extracting and using mineral resources, case studies Food resources: World food problems, changes caused by agriculture and overgrazing, effects of modern agriculture, fertilizer-pesticide problems, water logging, salinity, case studies Energy resources: Growing energy needs, renewable and nonrenewable energy sources, use of alternate energy sources. case studies Land resources: Land as a resource, land degradation, man induced landslides, soil erosion and desertification role of an individual in conservation of natural resources Equitable use of resources for sustainable lifestyles. Field study of local area to document environmental assets river / forest / grassland /hill / mountain.
